Canon 300D - focus problems

Hi folks,

I am thinking about to buy the Canon 300D but now I read in a german
journal that most digital SLRs have problems in getting the correct
focus. The focus is (depending on the used lense) more in the back or
more in the front of the object that has been targetted.

Who understands german:

They say, that reasons for these problems are
- bad justified AF sensors
- cover glass of CCD/CMOS sensor affects optical behaviour
(affects path of the light rays)
- digital cameras are more sensitive on inaccurate focus
- ...

My question: What are your experiences with focusing problems using
digital SLR cameras, especially with the Canon 300D?

Greetings, Martin.

I never had any problems with this. Mine works very reliable. You have
to be aware though, that you can manually change the focus points. Lets
say you take a macro shot. The camera uses a 7 point AF system that
tries to keep most of the image in focus. Since the DOF is very small
when doing macro, your subject might be out of focus. But this is a
natural limitation. You can counter by selecting a specific focal point
and making sure that the camera focuses on your subject.
The images on my website are all taken with this camera. I have two
images there that are not 100% sharp, but this is due to shaking not
focus problems.
It's an interesting article though and I will try to replicate it with
my 300D (once its back from repair).

Stay away from both the Canon 10D and 300D for design flaws in the AF
system. Virtually all honest Canon users are now admitting there is a
major problem with both of these cameras, now that Canon, with the
release of the 20D, claims to have implemented a fix the camera's AF
system.

It remains to be seen if the 20D's AF system will work properly or if
it will fail to the same degree. I shoot the 10D all the time and AF
is 60/40 in favor of out of focus results, even when a shot is lined
up very carefully--it doesn't matter what you do, it'll usually miss.

The 10D/300D also has the worst dynamic range of any DSLR by a wide
margin, due to Canon's low tech CMOS fabrication ('486 era 0.35u fab).
It is entirely unusable outdoors with bright highlights in the scene.
Again, Canon users are the complainers:

The 20D is actually a downgrade there, due to truly tiny pixel pitch.
Noise is high too, noticably worse than the already very noisey 10D as
tested by dpreview:

Avoid.

I note the use of the word 'all' there - finally given up on the Sigma ****e
then George? Given up trying to get it to work properly have you?

It remains to be seen if George will ever get a clue.
